Double Cab specific fitment. Deep V6 resonance. Built for Africa's toughest conditions.
Why Upgrade to a DeGraaf Exhaust?
Maximise the power and efficiency of your 1GR-FE engine with the DeGraaf Performance Exhaust System — specifically engineered for the Toyota Land Cruiser 79 Series 4.0 V6 Double Cab. This is not a generic bolt-on. The intermediate pipe is extended to perfectly suit the Double Cab chassis, ensuring a precise, rattle-free fit every time.
This full upgrade features precision-designed performance branches and high-flow stainless steel piping that optimises exhaust scavenging for maximum kilowatt and torque gains. By drastically reducing backpressure, this system improves throttle response and enhances fuel efficiency — making it the ultimate modification for heavy-duty overlanding and family adventures. Finished with the iconic DeGraaf Growl: a deep, sophisticated V6 tone without intrusive highway drone.
